I’ve owned two different series of Drobo and found performance to be unacceptable. OP reports 120MBytes/s (which is 960Mbits/s) which is about 3x the theoretical maximum of the claimed 802.11n link used (300Mb/s max). I can only conclude that OP is either making numbers up or is confused about the measurements, but there is no way a Drobo is going to saturate a gigabyte link. If OP is reading comments, please post up some factual perf numbers from a reputable benchmark tool.
